Abstract (en)
A spatial light modulator of the diffractive type comprises rows and columns of pixels (3, 3'). Row electrodes 4 are connected to a strobe signal generator 27 and column electrodes are connected to a data signal generator 25. The column electrodes comprise a first elongate electrodes 1 which are connected together and to the data signal generator 25. The column electrodes further comprise second elongate electrodes 2 which are connected together, are interdigitated with the first electrodes, and are connected to the data signal generator 25. In each row, apart from the end pixels, each pixel has its first electrodes 1 connected to the second electrodes of the preceding pixel and its second electrodes 2 connected to the first electrodes 1' of the succeeding pixel. <IMAGE>
